A rectangular loop consists of 80 turns, each carrying a current 8
liberstina [14]

Magnetic moment of loop is given by the formula

M = NiA

M = 80*8 *0.4*0.3

M = 76.8

now magnetic field is given here

B = 40 * 10^{-3} T

Now the torque on the loop is given by

T = MBsin\theta

T = 76.8* 40*10^{-3}*sin30

T = 1.536 Nm

so above is the torque on the loop.

g100num [7]

Based on Einstein's theory of gravity, if the sun and its mass were to suddenly disappear, earth would stay in its current orbit for a few minutes before taking off into space.

<h3>What would occur to our world if the sun were to suddenly vanish?</h3>

The Earth would be drawn to a new center of gravity if the sun disappeared. Earth's gravity would change, as would that of the rest of the solar system, and Earth would begin to drift into space since there would no longer be a steady source of energy from the sun. It is a foolish dream to think that life could exist without the sun forever. Humans could be able to survive for a while in some sort of base, such as a nuclear-powered dome.

The good news is that there wouldn't be many living things for the radioactive waste to endanger; however, there also probably wouldn't be any liquid water to cool the power system. All photosynthetic species, including plants and algae, would die if just the sun's light persisted.

Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its te
alexgriva [62]

Answer:

4.9 minutes

Explanation:

Given; T(t) = Ce^-kt + Ts

Now;

T(t) = 190 degrees Fahrenheit

Ts = 60 degrees

To obtain C;

190 = Ce^0 + 60

190 - 60 = C

C = 130

Hence, to find k when t=11

172 = 130 e^-11k + 60

172 -60/130 = e^-k

e^-k = 0.86

ln(e^-k) = ln( 0.86)

-k = -0.15

k = 0.15

Hence at 122 degrees, t is;

T(t) = Ce^-kt + Ts

122 = 130e^-0.15t + 60

122 - 60/130 = e^-0.15t

0.477 = e^-0.15t

ln (e^-0.15t) = ln (0.477)

-0.15t = -0.74

t = 0.74/0.15

t = 4.9 minutes
